I have an '06 SR5 4WD V6 - completely stock (17 in wheels) with about 65k miles. BTW, my H/T-S' are the GO51 models (there are several variants out there). They're good looking tires, too.
I struggled with deciding between all seasons or ATs, and the ratings over at Tire Rack showed very good numbers for wet and snow traction for the Geos. In the end, it came down to the Geos, Destination ATs, and some Toyo OCs with the Geos coming out on top due to overall ratings, price and availability (so much for customer survey quality). Maybe the Geos are better suited for pickups or smaller crossover vehicles, I don't know - but my original Duelers with ~ 55k miles had better performance than the new Yokos. A buddy with a Taco has the Geos and he likes them - but I had a '91 pickup and a '99 TRD Taco (bought back and crushed by Toyota due to the frame rust issue) and those trucks gripped the road better than any other vehicle I've ever owned, regardless of the tires. :cry2:
I wish I had gone with the Firestone or Toyo tires. With winter coming - I have to decide whether to suffer through another white knuckle snow season or bite the bullet and scrap the Geolanders. It's not like I have ~$800 sitting around waiting to be spent - but if these tires perform like they did last year I have to take into account my own safety driving in snowy conditions. I have no axe to grind with Yoko - but these tires really are that bad, IMO.
